2 Claims. (Cl. 160-104) This invention relates to jalousies and more particularly to a jalousie adapted to be permanently secured in the lower portion of a window frame which will permit the lowering of the lower sash if desired and which will effectively prevent the entry of rain and at the same time exclude intruders even with the lower sash open.

In the past many defects have been inherent in jalousies. Either they were to complicated and cumbersome to be produced and marketed at a reasonable enough figure to be within reach of a wide market or else they were unsightly and difficult to secure within the standard window frame. Jalousies have been provided which permit the lowering of the lower sash but were crude necessitating means for altering the normal position of the jalousie within the frame so as to permit the lowering of the lower frame.

Accordingly, it is an object of this invention to provide a simple device which may be inexpensively constructed and which may be permanently positioned within the window frame and which will permit the lowering of the lower sash without adjusting the jalousie in any way.

Another object of this invention is to provide a jalousie which will be simple and attractive in appearance and which may be permanently secured within the frame of a window and which will efiectively prevent the entry of intruders and, at the same time permit the lowering of the lower sash.

Another object of this invention is to provide an assem bly which may be simply installed by even the most unskilled person and which will be attractive in appearance and eminently suited to the prevention of the entry of rain and intruders into the home.

I accomplish these and other objects of my invention by providing a window guard assembly comprising a pair of vertical, aligned, horizontally spaced frame members having a plurality of vertically spaced aligned slots therein inclined downwardly toward the front, means for fastening said frame members to opposite window jambs countersunk within said slots, a plurality of glass slats positioned within said slots over said fastening means, strips of substantially the same width as said frame members running the length of the inside of said frame members for confining the glass slats within the slots and means for securing said slats within said slots from the outside so that the slats can be removed only from the inside whereby the assembly cannot be disassembled from the outside. I a

I further accomplish the objects of my invention by providing wooden frame members having in addition to the above mentioned features a vertical groove positioned on the inside edge so that fastening means may be passed through an outside strip countersunk therein and passed through frame members, and secured on the inside within said vertical groove and the inside portion of the frame may be covered by a strip to prevent removal of the slats from the inside.

2,852,071 Patented Sept. 16, 1958 A modification is provided employing extruded shapes, preferably of aluminum, for the frame members which are hollow and generally rectangular in shape. Slots are provided to position the slats together with a similar strip to prevent the removal of the slats from the rear.

While some of the objects have been set out above others will appear to those skilled in the art relating to ventilating devices, when the specification is read in connection with the accompanying drawing in which:

Fig. 1 is a perspective view showing my improved jalousie operatively positioned within a window frame with parts broken away for purposes of illustration,

Fig. 2 is a sectional view taken through the window frame and jalousie looking from the right hand side of Fig. 1,

Fig. 3 is an enlarged perspective view taken substantially along the line 3-3 in Fig. 1 with parts broken away and,

Fig. 4 shows a modified form of my invention looking from the outside of the window, with parts broken away.

Referring more particularlyto the drawing the numeral 10 broadly designates a window frame of conventional construction positioned within the walls of a house broadly designated at 12. The frame 10 comprises a lower sill 14 having a cut out portion so that the screened frame 16 may fit snugly thereagainst and permit the screen 18 positioned within the frame 16 to be disposed vertically in front of the window. Side windowv molding 20 is provided and has a pair of vertical sash guides 24 for the upper sash 26 and 28 for the lower sash 30.

Molding 32 is provided for confining the sash 30 fromthe inside.

struction and it is to be understood that the versatile window guard assembly to be described below could be employed with any type window frame.

The window frame assembly is shown associated with the lower portion of the window frame 10 in Figs. 1 and 2. The assembly chiefly consists of a pair of vertically disposed frame members broadly designated at 36 and 38, one of these being disposed vertically on each side of the window frame and just forwardly of the guide 28 for the lower sash 30. This permits the-lower sash to be lowered when desired, such as in cold weather. It will be noted that the upper sash fits snugly against the top of the frame members 36 and 38. The frame members 36 and 38, which may be constructed of any suit-, able material such as wood, would normally be provided in standard lengths to accommodate standard sizes of windows but a frame that proved to be too long could easily be cut off to accommodate a smaller window.

It will be noted that the frame members 36 and 38 maybe provided with cut out portions facing outwardly at the bottom and are designated at 36a and 38a, respectively. These cut out portions provide clearance for any of the standard latch means (not shown) which are normally associated with the screen frame 16.

A plurality of vertically spaced aligned slots 40 which incline downwardly toward the front are provided on the outside of the frame members 36 and 38 and are adapted to support the' s1ats 42. A number of screws 44 spaced would be hardly noticeable. The slats incline downwardly, preferably at an angle of about 45 so -as -to be effective in excluding rain. The heat absorbing glass is preferable since it would be more effective in preventing heat from the sun fromenter ing the house. If desired, of course, frosted glass could beemployed toaconstr-uct the slats 42. I

It will be noted that the slots 40 are-spaced somewhat closer together at the bottom adjacent-j'the -cut out portions 36a and 38a since the slats cannot be as wide at this point in some windows, depending upon what type latch means are-employed with the screens. It will also be noted that means in the form of a vertically disposed slat 46 is provided at the top to afford a bathe-to prevent rain from entering at this point. If desired-the sash 30 could be lowered to a small extent as shown in Figs. 1 and 2 to prevent this-entry of rain which would not necessitatethe use of the slat 46.

It will be noted, that vertically disposed strips 48, preferably of aluminum, are provided to fit over the outside edges of the frame members 36 and 38 to confine the slats 42 within the slots 40. It is, of course, preferred that noncorrosive material such as aluminum be employed throughout in the construction of the window guard assembly.

It will be noted that nails '50, also preferably of aluminum are driven through the frame members 36 and 38 and are'countersunk in the strips 48 so that they cannot be removed from the outside. A vertically disposed groove or slot 52 is provided on the inside edge of the members 36 and 38 and the nails 50 are bent down as at 50a within the slots 52. While it is preferable that nails be employed for this purpose it is to be understood that screws or other fastening means could be employed to advantage. Strips 60 are provided to cover the slots 52 and to confine the slats 42 within the slots 40 from the inside and are suitable secured to the frame members 36 and 38as by screws 62. The screws '62 and strips 60 may be easily removed so that the slats may be dismantled for cleaning.

It will be noted that this means .of fastening the slats 42 within the slots 40 makes it impossible to disassemble the window guard from the outside and would thus prevent the entry of unauthorized persons into the house. This feature permits the occupant to leave his 'home un attended and with the lower .sash raised without danger from rain or intruders.

A modified form of the invention is-shown in'Fig'. 4 and the corresponding parts-are indicated by prime notations. In the modified form the frame member 38 is shown constructed from a hollow metal, preferably aluminum, extrusion having slots 40' cut therein which incline downwardly toward the front and are suitably spaced. Means are thus provided 'for preventing the 'removal of the slats 42 from-the front. A vertically disposed strip 60' is suitably secured as by screws 62' to the inside of the frame 38. The frame member 38 is secured to the window frame-20 in a similar manner to that previously described was to prevent removal from the outside. It will be noted that serews44 which are aligned with the slots 40' are provided for-that purpose.

It is thus seen thatl have provideda novel window jalousie which is extraordinarily versatile and whichcan be employed with any window of standard design and although almost unnoticeable provides a simple and :attractive appearance upon closer inspection. The combined features of preventing the entry of intruders from the outside while at the same time permitting the lower sash to remain open makes it possible for a person to leave his home even in viewof threatening weather without fear of damage of rain or the entry of intruders. If desired the lower sash may be lowered in cold weather without any adjustment of the window guard assembly. The window guard assembly is simple to install and once having been installed is thus permanent requiring no further adjustments, and because of this simple construction every home owner could aflord them.

While a preferred embodiment of my invention has been described using specific terms, such description is for illustrative purposes only, and it is to be understood that changes and variations may bernade-without departing from the spirit or scope of the invention as defined by the appended claims.
